Application filed November 213, 19522. Serial No. 600.601.

To all whom it may concern:

Be it known that l. NICHOLAS Ar. Mona citizen of the United States, residing at Chicago Heights, in the county of Cook and State of lllinois, have invented new and useful improvements in Attachments for Hair Clippers, of which the following is a specification.

This invention relates to hair clippers for use by barber-s and others, and has for its object the provision of a novel rotary fan structure for producing a current of air which will positively force out all the out hairs and prevent any from remaining in the clipper mechanism.

It is a well known fact that when hair clippers are used some hairs adhere to the teeth and cutting mechanism thereof and it is also well known that it is a practice of barbers to blow on the clippers at intervals in the endeavor to remove the hair therefrom. This practice is entren'iely unsanitary as will naturally be apparent to a thinking person and it is with these facts in view that l have designed the present invention.

An additional and more specific object is the provision in hair clippers of a rotary blower structure operated by the movable element which effects movement of the cut ting blade and which operates to blow a blast of air of sufficient strength to blow away all the hair.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, highly efficient in use, durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of clippers equipped with my device.

Figure 2 is a horizontal section and Figure 3 is a vertical longitudinal section.

Referring more particularly to the drawings l have illustrated a conventional type of clippers including a casing it into which extends a rotary shaft B driven by any suitable flexible shafting connected with a motor. At its opposite end this casing carries the usual guard fingers G with which cooperate a blade D which is movable back and forth laterally of the casing and which 1s guided in its movement by means of screws or the like E which pass through a slot F. The inside or rear edge of the blade is formed with rack teeth G with which meshes a segmental gear l-ll formed on the head I of an operating bar d which is pivoted intermediate its ends as shown at lil and which has its free end formed with spaced arms lL between which is engaged an eccentric M carried by a shaft N upon which is mounted a worm wheel meshing with a worm P on the shaft B.

In the operation of this type of clipper it will be apparent that when the shaft 18 is rotated the worm F drives the worm wheel U and shaft N whereupon the eccentric M engaging the arms L rocks the bar back and forth for imparting reciprocatory movement to the blade D.

lfn carrying out my invention it provide a hood mounted exteriorly upon the top of the casing A and including a circular portion 11 and a flaring tunnel portion 12 which extends to the cutting end of the device. This hood might be secured in place by any desired means, though in actual practice l. have shown it as formed with attaching feet 13 which are riveted or otherwise secured to the casing A as shown at 14-. lit is preferable that the turn nel portion 12 of the hood be longitudinally curved as shown in Figure 3 to conform more or less to the shape of the casing A.

Journaled through the top of the casing A and bearing in a socket 15 in the bottom thereof is a shaft 16 which carries a blower Wheel 17 of ordinary construction located within the circular portion 11 of the hood. Also mounted upon the shaft 16 is a pinion 18 meshing with the worm wheel or gear When the clippers are in operation, it is apparent that the gear U driving the pinion 18 will rotate the shaft 16 and blower fan 17 which will operate to suck in air through holes 19 in the circular p0rtion 11 of the hood and force out this air through the tunnel member 12. The air issuing from the tunnel will impinge against the guard teeth 0 and blade and consequently blow away any hair which migl'it otherwise collect thereon. The blower operates automatically while the clippers are in use and it is apparent that lltl the attachment will thus operate as a great sanitary safe guard.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention I claim:

In combination with hair clippers having gear means for reciprocating a cutting blade; a blower attachment consisting of a hood mounted u on the casing of the clippers, and inclu ing a circular portion and a tunnel portion leading to the guard teeth and cutting blade of the clippers, a blower fan located within the circular portion of the hood and carried by a shaft journaled through the casing, and a pinion on said shaft meshing with the driving gear of the clipper mechanism.

In testimony whereof I afiix my signature. 25
